The 10th Rifle Division was a military formation of the Red Army. It existed by 1920, but was formally created on 20 June 1922, based on the 29th Infantry Brigade. It was then recreated at Vladimir in September 1939, and fought in the Second World War.

Contents

Around 1939, the division was stationed in the Leningrad Military District, Western Special Military District, and the Baltic Special Military District. It participated in the Polish campaign in 1939, and in the accession of Lithuania to the USSR in June 1940.

Soviet Union
–
The Soviet Union, officially the Union of Soviet Socialist Republics was a socialist state in Eurasia that existed from 1922 to 1991. It was nominally a union of national republics, but its government. The Soviet Union had its roots in the October Revolution of 1917 and this established the Russian Socialist Federative Soviet Republic and started the Russian Civil War between the revolutionary Reds and the counter-revolutionary Whites. In 1922, the communists were victorious, forming the Soviet Union with the unification of the Russian, Transcaucasian, Ukrainian, following Lenins death in 1924, a collective leadership and a brief power struggle, Joseph Stalin came to power in the mid-1920s. Stalin suppressed all opposition to his rule, committed the state ideology to Marxism–Leninism. As a result, the country underwent a period of rapid industrialization and collectivization which laid the foundation for its victory in World War II and postwar dominance of Eastern Europe. Shortly before World War II, Stalin signed the Molotov–Ribbentrop Pact agreeing to non-aggression with Nazi Germany, in June 1941, the Germans invaded the Soviet Union, opening the largest and bloodiest theater of war in history. Soviet war casualties accounted for the highest proportion of the conflict in the effort of acquiring the upper hand over Axis forces at battles such as Stalingrad. Soviet forces eventually captured Berlin in 1945, the territory overtaken by the Red Army became satellite states of the Eastern Bloc. The Cold War emerged by 1947 as the Soviet bloc confronted the Western states that united in the North Atlantic Treaty Organization in 1949. Following Stalins death in 1953, a period of political and economic liberalization, known as de-Stalinization and Khrushchevs Thaw, the country developed rapidly, as millions of peasants were moved into industrialized cities. The USSR took a lead in the Space Race with Sputnik 1, the first ever satellite, and Vostok 1. In the 1970s, there was a brief détente of relations with the United States, the war drained economic resources and was matched by an escalation of American military aid to Mujahideen fighters. In the mid-1980s, the last Soviet leader, Mikhail Gorbachev, sought to reform and liberalize the economy through his policies of glasnost. The goal was to preserve the Communist Party while reversing the economic stagnation, the Cold War ended during his tenure, and in 1989 Soviet satellite countries in Eastern Europe overthrew their respective communist regimes. This led to the rise of strong nationalist and separatist movements inside the USSR as well, in August 1991, a coup détat was attempted by Communist Party hardliners. It failed, with Russian President Boris Yeltsin playing a role in facing down the coup. On 25 December 1991, Gorbachev resigned and the twelve constituent republics emerged from the dissolution of the Soviet Union as independent post-Soviet states

Red Army
–
The Workers and Peasants Red Army was the army and the air force of the Russian Soviet Federative Socialist Republic, and after 1922 the Union of Soviet Socialist Republics. The army was established immediately after the 1917 October Revolution, the Bolsheviks raised an army to oppose the military confederations of their adversaries during the Russian Civil War. The Red Army is credited as being the land force in the Allied victory in the European theatre of World War II. During operations on the Eastern Front, it fought 75%–80% of the German land forces deployed in the war, inflicting the vast majority of all German losses and ultimately capturing the German capital. In September 1917, Vladimir Lenin wrote, There is only one way to prevent the restoration of the police, at the time, the Imperial Russian Army had started to collapse. The Tsarist general Nikolay Dukhonin estimated that there had been 2 million deserters,1.8 million dead,5 million wounded and 2 million prisoners and he estimated the remaining troops as numbering 10 million. Therefore, the Council of Peoples Commissars decided to form the Red Army on 28 January 1918 and they envisioned a body formed from the class-conscious and best elements of the working classes. All citizens of the Russian republic aged 18 or older were eligible, in the event of an entire unit wanting to join the Red Army, a collective guarantee and the affirmative vote of all its members would be necessary. Because the Red Army was composed mainly of peasants, the families of those who served were guaranteed rations, some peasants who remained at home yearned to join the Army, men, along with some women, flooded the recruitment centres. If they were turned away they would collect scrap metal and prepare care-packages, in some cases the money they earned would go towards tanks for the Army. Nikolai Krylenko was the supreme commander-in-chief, with Aleksandr Myasnikyan as deputy, Nikolai Podvoisky became the commissar for war, Pavel Dybenko, commissar for the fleet. Proshyan, Samoisky, Steinberg were also specified as peoples commissars as well as Vladimir Bonch-Bruyevich from the Bureau of Commissars, at a joint meeting of Bolsheviks and Left Socialist-Revolutionaries, held on 22 February 1918, Krylenko remarked, We have no army. The Red Guard units are brushed aside like flies and we have no power to stay the enemy, only an immediate signing of the peace treaty will save us from destruction. This provoked the insurrection of General Alexey Maximovich Kaledins Volunteer Army in the River Don region, the Treaty of Brest-Litovsk aggravated Russian internal politics. The situation encouraged direct Allied intervention in the Russian Civil War, a series of engagements resulted, involving, amongst others, the Czechoslovak Legion, the Polish 5th Rifle Division, and the pro-Bolshevik Red Latvian Riflemen. The Whites defeated the Red Army on each front, Leon Trotsky reformed and counterattacked, the Red Army repelled Admiral Kolchaks army in June, and the armies of General Denikin and General Yudenich in October. By mid-November the White armies were all almost completely exhausted, in January 1920, Budennys First Cavalry Army entered Rostov-on-Don. 1919 to 1923 At the wars start, the Red Army consisted of 299 infantry regiments, Civil war intensified after Lenin dissolved the Russian Constituent Assembly and the Soviet government signed the Treaty of Brest-Litovsk, removing Russia from the Great War

Division (military)
–
A division is a large military unit or formation, usually consisting of between 10,000 and 20,000 soldiers. Infantry divisions during the World Wars ranged between 10,000 and 30,000 in nominal strength, in most armies, a division is composed of several regiments or brigades, in turn, several divisions typically make up a corps. In the West, the first general to think of organising an army into smaller units was Maurice de Saxe, Marshal General of France. He died at the age of 54, without having implemented his idea, victor-François de Broglie put the ideas into practice. He conducted successful practical experiments of the system in the Seven Years War. The first war in which the system was used systematically was the French Revolutionary War. It made the more flexible and easy to manoeuvre. Under Napoleon, the divisions were grouped together into corps, because of their increasing size, napoleons military success spread the divisional and corps system all over Europe, by the end of the Napoleonic Wars, all armies in Europe had adopted it. In modern times, most military forces have standardized their divisional structures, the peak use of the division as the primary combat unit occurred during World War II, when the belligerents deployed over a thousand divisions. With technological advances since then, the power of each division has increased. Divisions are often formed to organize units of a particular type together with support units to allow independent operations. In more recent times, divisions have mainly been organized as combined arms units with subordinate units representing various combat arms, in this case, the division often retains the name of a more specialized division, and may still be tasked with a primary role suited to that specialization. For the most part, large cavalry units did not remain after World War II, in general, two new types of cavalry were developed, air cavalry or airmobile, relying on helicopter mobility, and armored cavalry, based on an autonomous armored formation. The former was pioneered by the 11th Air Assault Division, formed on 1 February 1963 at Fort Benning, on 29 June 1965 the division was renamed as the 1st Cavalry Division, before its departure for the Vietnam War. After the end of the Vietnam War, the 1st Cavalry Division was reorganised and re-equipped with tanks, the development of the tank during World War I prompted some nations to experiment with forming them into division-size units. Many did this the way as they did cavalry divisions, by merely replacing cavalry with AFVs. This proved unwieldy in combat, as the units had many tanks, instead, a more balanced approach was taken by adjusting the number of tank, infantry, artillery, and support units. A panzer division was a division of the Wehrmacht and the Waffen-SS of Germany during World War II

Infantry
–
Infantry is the general branch of an army that engages in military combat on foot. As the troops who engage with the enemy in close-ranged combat, infantry units bear the largest brunt of warfare, Infantry can enter and maneuver in terrain that is inaccessible to military vehicles and employ crew-served infantry weapons that provide greater and more sustained firepower. In English, the 16th-century term Infantry describes soldiers who walk to the battlefield, and there engage, fight, the term arose in Sixteenth-Century Spain, which boasted one of the first professional standing armies seen in Europe since the days of Rome. It was common to appoint royal princes to military commands, and the men under them became known as Infanteria. in the Canadian Army, the role of the infantry is to close with, and destroy the enemy. In the U. S. Army, the closes with the enemy, by means of fire and maneuver, in order to destroy or capture him, or to repel his assault by fire, close combat. In the U. S. Marine Corps, the role of the infantry is to locate, close with, and destroy the enemy fire and maneuver. Beginning with the Napoleonic Wars of the early 19th century, artillery has become a dominant force on the battlefield. Since World War I, combat aircraft and armoured vehicles have become dominant. In 20th and 21st century warfare, infantry functions most effectively as part of a combined arms team including artillery, armour, Infantry relies on organized formations to be employed in battle. These have evolved over time, but remain a key element to effective infantry development and deployment, until the end of the 19th century, infantry units were for the most part employed in close formations up until contact with the enemy. This allowed commanders to control of the unit, especially while maneuvering. The development of guns and other weapons with increased firepower forced infantry units to disperse in order to make them less vulnerable to such weapons. This decentralization of command was made possible by improved communications equipment, among the various subtypes of infantry is Medium infantry. This refers to infantry which are heavily armed and armored than heavy infantry. In the early period, medium infantry were largely eliminated due to discontinued use of body armour up until the 20th century. In the United States Army, Stryker Infantry is considered Medium Infantry, since they are heavier than light infantry, Infantry doctrine is the concise expression of how infantry forces contribute to campaigns, major operations, battles, and engagements. It is a guide to action, not a set of hard, doctrine provides a very common frame of reference across the military forces, allowing the infantry to function cooperatively in what are now called combined arms operations. Doctrine helps standardise operations, facilitating readiness by establishing common ways of accomplishing infantry tasks, doctrine links theory, history, experimentation, and practice

Invasion of Poland
–
The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German-Soviet Frontier Treaty. German forces invaded Poland from the north, south, and west the morning after the Gleiwitz incident, as the Wehrmacht advanced, Polish forces withdrew from their forward bases of operation close to the Polish–German border to more established lines of defence to the east. After the mid-September Polish defeat in the Battle of the Bzura, Polish forces then withdrew to the southeast where they prepared for a long defence of the Romanian Bridgehead and awaited expected support and relief from France and the United Kingdom. While those two countries had pacts with Poland and had declared war on Germany on 3 September, in the end their aid to Poland was very limited. The Soviet Red Armys invasion of Eastern Poland on 17 September, in accordance with a protocol of the Molotov–Ribbentrop Pact. Facing a second front, the Polish government concluded the defence of the Romanian Bridgehead was no longer feasible, on 6 October, following the Polish defeat at the Battle of Kock, German and Soviet forces gained full control over Poland. The success of the invasion marked the end of the Second Polish Republic, the Soviet Union incorporated its newly acquired areas into its constituent Belarusian and Ukrainian republics, and immediately started a campaign of sovietization. In the aftermath of the invasion, a collective of underground resistance formed the Polish Underground State within the territory of the former Polish state. Many of the exiles that managed to escape Poland subsequently joined the Polish Armed Forces in the West. On 30 January 1933, the Nazi Party, under its leader Adolf Hitler, as part of this long-term policy, Hitler at first pursued a policy of rapprochement with Poland, trying to improve opinion in Germany, culminating in the German–Polish Non-Aggression Pact of 1934. Earlier, Hitlers foreign policy worked to weaken ties between Poland and France, and attempted to manoeuvre Poland into the Anti-Comintern Pact, forming a front against the Soviet Union. The Poles feared that their independence would eventually be threatened altogether, the so-called Polish Corridor constituted land long disputed by Poland and Germany, and inhabited by a Polish majority. The Corridor had become a part of Poland after the Treaty of Versailles, many Germans also wanted the city of Danzig and its environs to be reincorporated into Germany. Danzig was a city with a German majority. It had been separated from Germany after Versailles and made into the nominally independent Free City of Danzig, the series of border violations, which are unbearable to a great power, prove that the Poles no longer are willing to respect the German frontier. Poland participated with Germany in the partition of Czechoslovakia that followed the Munich Agreement and it coerced Czechoslovakia to surrender the region of Český Těšín by issuing an ultimatum to that effect on 30 September 1938, which was accepted by Czechoslovakia on 1 October. This region had a Polish majority and had been disputed between Czechoslovakia and Poland in the aftermath of World War I, the Polish annexation of Slovak territory later served as the justification for the Slovak state to join the German invasion. Poland rejected this proposal, fearing that after accepting these demands, it would become subject to the will of Germany

Siege of Leningrad
–
The siege started on 8 September 1941, when the last road to the city was severed. Although the Soviets managed to open a land corridor to the city on 18 January 1943. It was one of the longest and most destructive sieges in history, Leningrads capture was one of three strategic goals in the German Operation Barbarossa and the main target of Army Group North. By 1939 the city was responsible for 11% of all Soviet industrial output and it has been reported Adolf Hitler was so confident of capturing Leningrad that he had invitations printed to the victory celebrations to be held in the citys Hotel Astoria. According to a sent to Army Group North on 29 September, After the defeat of Soviet Russia there can be no interest in the continued existence of this large urban center. Following the citys encirclement, requests for surrender negotiations shall be denied, since the problem of relocating and feeding the population cannot, in this war for our very existence, we can have no interest in maintaining even a part of this very large urban population. Hitlers ultimate plan was to raze Leningrad to the ground and give areas north of the River Neva to the Finns, Army Group North under Feldmarschall Wilhelm Ritter von Leeb advanced to Leningrad, its primary objective. Finnish military forces were north of Leningrad, while German forces occupied territories to the south, thus, it is argued that much of the Finns participation was merely defensive. The Germans planned on lack of food being their weapon against the citizens. On 27 June 1941, the Council of Deputies of the Leningrad administration organised First response groups of civilians, in the next days, Leningrads civilian population was informed of the danger and over a million citizens were mobilised for the construction of fortifications. Several lines of defences were built along the perimeter to repulse hostile forces approaching from north and south by means of civilian resistance. In the south, the line ran from the mouth of the Luga River to Chudovo, Gatchina, Uritsk, Pulkovo. Another line of defence passed through Peterhof to Gatchina, Pulkovo, Kolpino, in the north the defensive line against the Finns, the Karelian Fortified Region, had been maintained in Leningrads northern suburbs since the 1930s, and was now returned to service. Even the guns from the cruiser Aurora were moved inland to the Pulkovo Heights to the south of Leningrad, the 4th Panzer Group from East Prussia took Pskov following a swift advance and managed to reach Novgorod by 16 August. The Soviet defenders fought to the death, despite the German discovery of the Soviet defence plans on an officers corpse, after the capture of Novgorod, General Hoepners 4th Panzer Group continued its progress towards Leningrad. However, the 18th Army — despite some 350,000 men lagging behind — forced its way to Ostrov and Pskov after the Soviet troops of the Northwestern Front retreated towards Leningrad. On 10 July, both Ostrov and Pskov were captured and the 18th Army reached Narva and Kingisepp, from where advance toward Leningrad continued from the Luga River line. This had the effect of creating siege positions from the Gulf of Finland to Lake Ladoga, the Finnish Army was then expected to advance along the eastern shore of Lake Ladoga

Vladimir, Russia
–
Vladimir is a city and the administrative center of Vladimir Oblast, Russia, located on the Klyazma River,200 kilometers to the east of Moscow. It is served by a railway and the M7 motorway, Vladimir was one of the medieval capitals of Russia, with significant buildings surviving from the 12th century. Two of its Russian Orthodox cathedrals, a monastery, and associated buildings have been designated as among the White Monuments of Vladimir and Suzdal, in the past, the city was also known as Vladimir-on-Klyazma and Vladimir-Zalessky, to distinguish it from another Vladimir in Volhynia. Traditionally, the date of Vladimir has been acknowledged as 1108. This view attributes the founding of the city, and its name, to Vladimir Monomakh and it is named there as Volodymyr. On the 17th centuries maps, it was identified as Wolodimer, being established long after the city of Volodymyr in Volhynia, initially it was named Vladimir-on-Klyazma. In 1958, the 850th anniversary of the city foundation was celebrated, in the 1990s, a new opinion developed that the city is older than this. The neighboring town of Suzdal, for instance, was mentioned in 1024 and its 12th-century inhabitants alluded to Vladimir as a young town and treated its rulers with arrogance. In the words of a chronicle, they said that the people of Vladimir were their kholops. In the seniority conflicts of the 12th and early 13th centuries, Vladimir was repeatedly described as a young town compared to Suzdal, nevertheless, the Charter of Vladimir, the basic law of the city passed in 2005, explicitly mentions 990 as the date of the citys foundation. The citys most historically significant events occurred after the turn of the 12th century, under Dolgorukys son, Andrey Bogolyubsky, the city became the center of the Vladimir-Suzdal Principality. It had a Golden Age, which lasted until the Mongol invasion of Rus in 1237, during this time, Vladimir enjoyed immense growth and prosperity. Andrey oversaw the building of the citys Golden Gates and the Dormition Cathedral, in 1164, Andrey attempted to establish a new metropolitanate in Vladimir, separate from that of Kiev. He was rebuffed by the Patriarch of Constantinople, scores of Russian, German, and Georgian masons worked on Vladimirs white stone cathedrals, monastery, towers, and palaces. Unlike any other buildings, their exterior was elaborately carved with high relief stone sculptures. Only three of these edifices stand today, the Dormition Cathedral, the Cathedral of Saint Demetrius, and they are included among the White Monuments of Vladimir and Suzdal, designated as a UNESCO World Heritage Site. During Andreys reign, a palace in Bogolyubovo was built, as well as the world-famous Church of the Intercession on the Nerl. Andrey was assassinated at his palace at Bogolyubovo in 1175, Vladimir was besieged by the Mongol-Tatars of the Golden Horde under Batu Khan

Eastern Front (World War II)
–
The battles on the Eastern Front constituted the largest military confrontation in history. They were characterized by unprecedented ferocity, wholesale destruction, mass deportations, and immense loss of life due to combat, starvation, exposure, disease, and massacres. The Eastern Front, as the site of nearly all extermination camps, death marches, ghettos, of the estimated 70 million deaths attributed to World War II, over 30 million, many of them civilian, occurred on the Eastern Front. The Eastern Front was decisive in determining the outcome of the European portion of World War II and it resulted in the destruction of the Third Reich, the partition of Germany for nearly half a century and the rise of the Soviet Union as a military and industrial superpower. The two principal belligerent powers were Nazi Germany and the Soviet Union, along with their respective allies. Though never engaged in action in the Eastern Front, the United Kingdom. The joint German–Finnish operations across the northernmost Finnish–Soviet border and in the Murmansk region are considered part of the Eastern Front, in addition, the Soviet–Finnish Continuation War may also be considered the northern flank of the Eastern Front. Despite their ideological antipathy, both Nazi Germany and the Soviet Union shared a dislike for the outcome of World War I. The Molotov–Ribbentrop Pact signed in August 1939 was an agreement between Nazi Germany and the Soviet Union. It contained a secret protocol aiming to return Central Europe to the pre–World War I status quo by dividing it between Germany and the Soviet Union, Finland, Estonia, Latvia and Lithuania would return to Soviet control, while Poland and Romania would be divided. I need the Ukraine so that they cant starve us out, the two powers invaded and partitioned Poland in 1939. The annexations were never recognized by most Western states, the annexed Romanian territory was divided between the Ukrainian and Moldavian Soviet republics. Adolf Hitler had argued in his autobiography Mein Kampf for the necessity of Lebensraum, acquiring new territory for Germans in Eastern Europe, Wehrmacht officers told their troops to target people who were described as Jewish Bolshevik subhumans, the Mongol hordes, the Asiatic flood and the red beast. The vast majority of German soldiers viewed the war in Nazi terms, Hitler referred to the war in unique terms, calling it a war of annihilation which was both an ideological and racial war. In addition, the Nazis also sought to wipe out the large Jewish population of Central, after Germanys initial success at the Battle of Kiev in 1941, Hitler saw the Soviet Union as militarily weak and ripe for immediate conquest. On 3 October 1941, he announced, We have only to kick in the door, thus, Germany expected another short Blitzkrieg and made no serious preparations for prolonged warfare. Throughout the 1930s the Soviet Union underwent massive industrialization and economic growth under the leadership of Joseph Stalin, Stalins central tenet, Socialism in one country, manifested itself as a series of nationwide centralized Five-Year Plans from 1929 onwards. It served as a testing ground for both the Wehrmacht and the Red Army to experiment with equipment and tactics that they would later employ on a wider scale in the Second World War

Estonia
–
Estonia, officially the Republic of Estonia, is a country in the Baltic region of Northern Europe. It is bordered to the north by the Gulf of Finland, to the west by the Baltic Sea, to the south by Latvia, across the Baltic Sea lies Sweden in the west and Finland in the north. The territory of Estonia consists of a mainland and 2,222 islands and islets in the Baltic Sea, covering 45,339 km2 of land and water, and is influenced by a humid continental climate. The territory of Estonia has been inhabited since at least 6500 BC, in 1988, during the Singing Revolution, the Estonian Supreme Soviet issued the Estonian Sovereignty Declaration in defiance of Soviet rule, and independence was restored on 20 August 1991. Estonia is a parliamentary republic divided into fifteen counties. Its capital and largest city is Tallinn, with a population of 1.3 million, it is one of the least-populous member states of the European Union, Eurozone, North Atlantic Treaty Organization, OECD and Schengen Area. Estonia is a country with an advanced, high-income economy that is among the fastest growing in the EU. Its Human Development Index ranks very highly, and it performs favourably in measurements of economic freedom, civil liberties, the 2015 PISA test places Estonian high school students 3rd in the world, behind Singapore and Japan. Citizens of Estonia are provided with health care, free education. Since independence the country has developed its IT sector, becoming one of the worlds most digitally advanced societies. In 2005 Estonia became the first nation to hold elections over the Internet, in the Estonian language, the oldest known endonym of the Estonians was maarahvas, meaning country people or people of the land. The land inhabited by Estonians was called Maavald meaning Country Parish or Land Parish, one hypothesis regarding the modern name of Estonia is that it originated from the Aesti, a people described by the Roman historian Tacitus in his Germania. The historic Aesti were allegedly Baltic people, whereas the modern Estonians are Finno-Ugric, the geographical areas between Aesti and Estonia do not match, with Aesti being further down south. Ancient Scandinavian sagas refer to a land called Eistland, as the country is called in Icelandic. Early Latin and other ancient versions of the name are Estia and Hestia, esthonia was a common alternative English spelling prior to 1921. Human settlement in Estonia became possible 13,000 to 11,000 years ago, the oldest known settlement in Estonia is the Pulli settlement, which was on the banks of the river Pärnu, near the town of Sindi, in south-western Estonia. According to radiocarbon dating it was settled around 11,000 years ago, the earliest human inhabitation during the Mesolithic period is connected to Kunda culture, which is named after the town of Kunda in northern Estonia. At that time the country was covered with forests, and people lived in communities near bodies of water

Until World War II, Latvia also had significant minorities of ethnic Germans, Latvia is historically predominantly Protestant Lutheran, except for the Latgale region in the southeast, which has historically been predominantly Roman Catholic. The Russian population has brought a significant portion of Eastern Orthodox Christians. The Republic of Latvia was founded on 18 November 1918, however, its de facto independence was interrupted at the outset of World War II. The peaceful Singing Revolution, starting in 1987, called for Baltic emancipation of Soviet rule and it ended with the Declaration on the Restoration of Independence of the Republic of Latvia on 4 May 1990, and restoring de facto independence on 21 August 1991. Latvia is a democratic and developed country and member of the European Union, NATO, the Council of Europe, the United Nations, CBSS, the IMF, NB8, NIB, OECD, OSCE, and WTO. For 2014, Latvia was listed 46th on the Human Development Index and it used the Latvian lats as its currency until it was replaced by the euro on 1 January 2014. The name Latvija is derived from the name of the ancient Latgalians, one of four Indo-European Baltic tribes, henry of Latvia coined the Latinisations of the countrys name, Lettigallia and Lethia, both derived from the Latgalians. The terms inspired the variations on the name in Romance languages from Letonia. Around 3000 BC, the ancestors of the Latvian people settled on the eastern coast of the Baltic Sea. The Balts established trade routes to Rome and Byzantium, trading local amber for precious metals, by 900 AD, four distinct Baltic tribes inhabited Latvia, Curonians, Latgalians, Selonians, Semigallians, as well as the Livonians speaking a Finnic language
